Background: Two novel HER2 aptamers were recently selected with great potential for the in vitro diagnosis of HER2-positive cancer. The goal of this study was to examine the in vivo diagnostic potential of these HER2 aptamers. Methods: Both HER2 aptamers were radiolabelled with 68Ga, injected in mice bearing a HER2-positive and HER2-negative tumour and evaluated by PET/MRI. Results: Ex vivo bio...

We report a case of a 56-year-old woman diagnosed with infiltrating ductal carcinoma of the left breast, who had undergone left modified radical mastectomy followed by radiotherapy and adjuvant chemotherapy. FDG PET-CT showed metastatic brachial plexopathy with intra-spinal and extra-axial brain metastasis. Metastatic brachial plexopathy along with brain and spinal metastasis is a rare conditio...

Small animal neuroimaging has become increasingly available to researchers, expanding the breadth of questions studied with these methods. Applying these noninvasive techniques to the open questions underlying epileptogenesis is no exception. A major advantage of small animal neuroimaging is its translational appeal. Studies can be well controlled and manipulated, examining the living brain in ...

Angiosarcoma is a neoplasm of an endothelial origin, which could arise from blood or lymphatic vessels, respectively hemangiosarcoma or lymphosarcoma. They account for only 0.1% of adult malignancies and represent 1–2% of all soft tissue sarcomas in humans [1]. Most tumours are malignant and readily give distant metastases because they are composed of rapidly proliferating and extensively infil...

Accurate diagnosis and staging are essential for an optimal management of cancer patients. Positron emision tomography with 2-deoxy-2-fluorine-18-fluoro-D-glucose ((18)FDG-PET) and, more recently, (18)FDG-PET/computed tomography ((18)FDG-PET/CT) have emerged as powerful imaging tools in oncology, because of the valuable functional information they provide. The combined acquisition of PET and CT...

A 65-year-old man with a history of lymphoma was referred for a positron emission tomography/ computed tomography (PET/CT) with 2-deoxy-2[18F]-fluoro-D-glucose F-(18FDG) study to evaluate a collection in the subcutaneous fat of the anterolateral upper abdomen reported on a CT scan. PET/CT scan (fig. 1) revealed mildly increased tracer activity localizing to multifocal discrete areas of haziness...

Very few data are available on the long-term changes in the cognitive abilities of patients with loss of psychic self-activation syndrome (LPSAS). Here, we present a 25-year follow-up study on a case of LPSAS resulting from bilateral pallidal lesions caused by carbon monoxide intoxication. Typical signs of LPSAS were observed, showing no changes in severity, but Ganser syndrome (GS) gradually d...

The present article describes the ongoing (partial) remission of a female patient (41 years old) from estrogen receptor (ER)-positive/progesterone receptor (PR)-negative metastatic breast cancer in response to a combination treatment directed towards the revitalization of the mitochondrial respiratory chain (oxidative phosphorylation), the suppression of NF-kappaB as a factor triggering the inf...
